Slow transaction processing

During my testing phase I discovered that the transaction speed is slow and takes quite a significant amount of times unto 15minutes for a single transaction to be processed, i would like the devs to look into this and comeup with and alternative solution. in all, the team did a fantastic job and i would love to say Kudos to you all.
